chore: switch to ty type checker ty is astral's new extremely fast python type checker written in rust. this replaces mypy in pre-commit with ty while keeping mypy for the pytest-mypy-plugins typesafety tests. starting with permissive rules - all existing errors are ignored for now and can be gradually enabled as we fix them. see https://astral.sh/blog/ty 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
